Dirty Fix

target_compile_options(mbedtls PRIVATE -Wno-format)

[davidhorstmann-arm]

Hi, thanks for this report!

Doing a bit of cursory research it looks like this might be related to the interplay between GNU and MSVC format specifiers. MinGW compiles using GCC, which does not understand Windows-specific format specifiers like %I64d, but it uses msvcrt to get its printf() implementation, so it needs to use them.

Are you able to find out exactly what MBEDTLS_PRINTF_LONGLONG is defined as in your build?

[dragonflylee]

try -DCMAKE_C_FLAGS="-D__USE_MINGW_ANSI_STDIO=0"

[CesarBerriot]

__USE_MINGW_ANSI_STDIO

It works (tested both Debug and Release build types), but breaks compatibility with older versions of windows (Windows XP and prior, which likely means that old Windows Embedded versions won't work either).

See https://sourceforge.net/p/mingw-w64/wiki2/gnu%20printf.

[davidhorstmann-arm]

I've raised a PR that might fix the issue (I haven't tried to reproduce it myself yet). @CesarBerriot does #10165 fix the issue?

[dragonflylee]

@davidhorstmann-arm it's introduce by #10020

[davidhorstmann-arm]

@davidhorstmann-arm it's introduce by #10020

Ah thanks, I hadn't noticed that, I'll take a look.

[CesarBerriot]

I've raised a PR that might fix the issue (I haven't tried to reproduce it myself yet). @CesarBerriot does #10165 fix the issue?

Configuration of your branch fails on my end.

This is how I fetched it:

FetchContent_Declare(mbedtls GIT_REPOSITORY https://github.com/davidhorstmann-arm/mbedtls.git GIT_TAG 440ce7550cbe7ebb531dbf4473821b22dd670e5f)

Fetching using the branch as the tag instead of the exact commit produces the same results.

Are you able to find out exactly what MBEDTLS_PRINTF_LONGLONG is defined as in your build?

include/mbedtls/debug.h Line 114

#if defined(__MINGW32__) || (defined(_MSC_VER) && _MSC_VER < 1900)
   #include <inttypes.h>
   #define MBEDTLS_PRINTF_SIZET     PRIuPTR
   #define MBEDTLS_PRINTF_LONGLONG  "I64d"
#else

Configuration of your branch fails on my end.

Ah yes, sorry, that'll be because the generated files are not there. We only check-in the generated files for release tags and we don't automatically generate them on Windows.

You can fix this by making sure that you have python and perl installed and then setting -DGEN_FILES=ON in your CMake command.

[davidhorstmann-arm]

My PR to fix this issue doesn't pass our own MinGW CI, so I'm currently seeing if I can find a fix for that.

Thanks 😄, I'll be back with results tomorrow.

My python version is 3.13.2 as confirmed by this line in the CMake configuration log:

To generate the intermediate files that aren't present except in official releases, you need some Python packages, as documented in the README. In 3.6, that's jsonschema and jinja2, or run python3 -m pip install --user -r scripts/basic.requirements.txt.

[davidhorstmann-arm]

In the meantime I have fiddled with #10165 a bit, it fixes the issue locally for me (whilst working with our CI MinGW as well). If you're able to get the Python dependencies sorted, try the new version and let me know if it works for you as well.

[CesarBerriot]

@davidhorstmann-arm try the new version and let me know if it works for you as well

Works 👍🏻 (still requires GEN_FILES to be ON).

@gilles-peskine-arm you need some Python packages, as documented in the README

Requiring python, perl and some python packages to be installed manually defeats the whole point of supporting fetchcontent integration.
